Description

Technical Field

[0001] This utility model relates to the field of photoelectric detection technology, and in particular to a rapid detection device for defects on the surface of photovoltaic module glass. Background Technology

[0002] With the increasing global demand for clean energy, the photovoltaic industry has developed rapidly. As the core component of photovoltaic power generation systems, the quality of photovoltaic modules directly affects power generation efficiency and service life. Glass is an important component of photovoltaic modules, located on the outermost layer, and plays an important role in protecting the internal cells and transmitting light. During the production process of photovoltaic modules, it is necessary to quickly and accurately detect defects on the glass surface to ensure product quality and meet the needs of large-scale, high-quality production in the photovoltaic industry.

[0003] Various defects on the glass surface, such as scratches, bubbles, cracks, and impurities, can significantly negatively impact the optical performance, mechanical properties, and weather resistance of photovoltaic modules. Specifically, scratches scatter and reflect light, reducing light transmittance; bubbles and cracks compromise the integrity of the glass, affecting its mechanical strength; and impurities interfere with the light transmission path. These defects not only weaken the photovoltaic module's ability to capture and convert light energy but also reduce its durability and stability under various environmental conditions, directly leading to a significant decrease in the power generation efficiency of the entire photovoltaic system. They also significantly reduce the system's reliability and lifespan. Existing manual visual inspection methods for checking glass surface defects allow for flexible observation of different areas of the glass surface based on experience and judgment, quickly identifying some obvious defects such as larger scratches, bubbles, and cracks. For irregularly shaped or uniquely located defects, visual inspection by workers is necessary, but this method is greatly affected by worker experience, fatigue levels, and environmental factors, resulting in low accuracy, a tendency to miss defects, and slow inspection speed, failing to meet the needs of large-scale production. Utility Model Content

[0032] Specifically, the bottom of the detection housing 1 is firmly fixed with multiple evenly distributed fixing blocks 3, which provide structural support and stability. A rotating shaft 4 is mounted in the center of each fixing block 3 via a rotatable connection, allowing for flexible rotation. A gear 2 5 is fixedly connected to the outer wall of the rotating shaft 4, playing a crucial role in the transmission process. A regularly shaped square opening 6 is located in the middle of the bottom of the detection housing 1, facilitating the installation and adjustment of internal components.

[0036] Specifically, the rotating shaft 4 is securely connected to a limiting plate 14 at its front side. The main function of the limiting plate 14 is to limit the range of motion and ensure the stable operation of the mechanism. Next, a rocker arm 15 is securely connected to the rear side of the limiting plate 14. The rocker arm 15 is manually operated to achieve specific actions of the mechanism. In addition, a protective shell 16 is precisely fixed to the top middle area of ​​the detection housing 1.

The function of the push rod 18 is to push the slider 17 with external force, thereby driving the operation of the entire mechanism.

[0037] Please see the appendix Figure 3 - Appendix Figure 5 The front side of the detection housing 1 is fixedly connected to the bracket 2 19, the top of the bracket 2 19 is fixedly connected to the main controller 20, the top of the carrier box 202 is provided with a rectangular opening 21, the left side of the carrier box 202 is slidably connected to the push column 22, the top of the push column 22 is fixedly connected to the limit plate 23, and the bottom of the push column 22 is fixedly connected to the tray 24.

[0038] Specifically, a sturdy bracket 29 is securely connected to the front of the detection housing 1 via a robust fixing device.

A regular rectangular opening 21 is opened in the top area of ​​the carrying box 202, facilitating the entry and exit of items and operation. A movable push column 22 is connected to the left side of the carrying box 202 via a flexible sliding connection device. A limiting plate 23 is securely connected to the top of the push column 22. The limiting plate 23 ensures that the push column 22 does not exceed a predetermined range during movement, maintaining operational precision. Similarly, a stable tray 24 is reliably fixed to the bottom of the push column 22. The tray 24 is used to carry and transport items, ensuring the stability and safety of the items during movement.

[0039] Working principle: Rotating the rocker arm 15 causes the rotating shaft 4 to drive the gear 5 to rotate. The top ring rack 7 meshes with the gear 5. The rotation causes the swing ring 8 to swing the top support ring 9, making the light more comprehensive. Rotating the push rod 18 causes the bottom slider 17 to drive the rotating ring 10 to rotate. The slider 17 slides on the top of the support ring 9, so that the two ring frames 11 inside the rotating ring 10 can illuminate the glass plate in the middle from all directions. The user operates the main controller 20 to take pictures and display them on the screen. This structure can enhance the light and make it easier to inspect the defects on the glass surface, meeting the user's needs.

[0040] During testing, the glass is placed on the tray 24, and the motor 203 is started, causing the worm gear 204 at the output end to rotate. This causes the worm wheel 205, which is meshed with the top, to drive the rotating column 206 to rotate. The gears 207, which are fixedly connected to the left and right sides, rotate, and the spur rack 208, which is meshed with the front side, moves the push column 22 downward, so that the tray 24 at the bottom carries the glass into the bottom testing housing 1 for testing. This eliminates the need for hands to enter the device, avoids errors that could damage internal parts, and extends the life of the equipment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
